I agree with your analysis, but not with your conclusion.

We can expect that the SMP version will not run much faster.  However,  
we might also hope that it does not run orders of magnitude slower.

At the moment, pthread based solutions are slaughtering Erlang, and  
also achieving up to 350% CPU utilization.
